Energy curable inks and other compositions incorporating surface modified, nanometer-sized particles
Patent number: 6467897Abstract: Compositions that incorporate relates to compositions that incorporate surface modified, nanometer sized, inorganic oxide particles into energy curable fluids. The surface modification aspect allows the compatibility between the particles and fluid to be controllably adjusted to achieve a wide range of rheological characteristics. For printing, preferred compositions have favorable dot gain and thickness build up. When the composition is cured, the presence of the particles also helps improve physical properties such as hardness, modulus, abrasion resistance, refractive index, and the like. The compositions are particularly well-suited for forming printed, radiation cured features on substrates such as paper, signs, walkways, roadways, motor vehicles, boats, aircraft, furniture, equipment, and the like.Type: GrantFiled: January 8, 2001Date of Patent: October 22, 2002Assignee: 3M Innovative Properties CompanyInventors: Dong Wu, Brant U.

Patent number: 6460254Abstract: Around a push button formed on an arm 3, teeth are disposed at a regular angle, and around the push button inserting hole in a handle 4 grooves are disposed corresponding to the teeth, thereby, by biasing the arm 3 with a compressed coil spring to engage the teeth with the grooves. Whereby, by pushing the push button to cause the arm to stroke, the engagement of the teeth and the groove is released to cause the arm 3 to turn and by freeing the push button the teeth and the grooves are engaged, thereby the arm 3 is positioned and held at a desired position.Type: GrantFiled: October 19, 2000Date of Patent: October 8, 2002Assignee: Carl Manufacturing Co., Ltd.Inventors: Makoto Mori, Xiao Dong Wu

Publication number: 20020086914Abstract: Low viscosity, radiation curable fluid formulations that can be used advantageously as radiation curable, inks. The formulations are easily prepared for use in ink jet systems. The viscosity of the compositions is low enough so that conventional solvent is not required in order to satisfy the requisite low ink jet viscosity specifications. After curing, the compositions form durable, weatherable, abrasion resistant, printed images on a wide variety of porous and nonporous substrates. The formulations are very suitable for outdoor printing applications, especially for printing outdoor graphics onto a variety of surfaces, including vinyl or other polymer films commonly used for signage, retroreflective signage or other retroreflective items.Type: ApplicationFiled: November 7, 2001Publication date: July 4, 2002Applicant: 3M Innovative Properties CompanyInventors: Jennifer L.

Patent number: 6100846Abstract: An antenna, particularly adapted to produce a scanning beam usable for radar and communication applications, includes a frame. Attached to the frame is a reciprocating device that is operatively connected to a reflecting conductor. Spaced by a uniform gap from the conductor is an elongated dielectric waveguide carried on a conductive layer of a laminate supported by the frame on an input side of the antenna. The waveguide covers a set of spaced apart apertures in the laminate conductive layer. Joined to the laminate conductive layer on an opposite output side of the antenna is a dielectric layer. On an outer surface of the laminate dielectric layer is a set of spaced apart conductive patches that align with the laminate conductive layer apertures. During operation of the antennas an electromagnetic wave is transmitted through the waveguide to pass through the laminate apertures and energizes the patches.Type: GrantFiled: March 9, 1999Date of Patent: August 8, 2000Assignee: Epsilon Lambda Electronics Corp.Inventors: David D.

Patent number: 6018096Abstract: A chimeric, non-human, genetically-immunocompetent mammal is disclosed. The hematopoietic system of the mammal has human passaged bone marrow stromal cells and human hematopoietic stem cells obtained from a CD34.sup.+ -enriched bone marrow fraction, and also contains transplanted syngeneic non-lymphoid spleen colony cells. The mammal may be a mouse, a rat, a rabbit, a cat, a dog, a pig, a sheep or a non-human primate. The mammal can be produced by providing a non-human, genetically-immunocompetent mammal in which its immunologic genotype comports with the norm for the species of the mammal, exposing the mammal to a level of x- or gamma-radiation that is sufficient to destroy substantially all bone marrow in the mammal to render the mammal phenotypically immunodeficient, then transplanting into the mammal syngeneic non-lymphoid spleen colony cells and human passaged bone marrow stromal cells, and transplanting into the mammal human hematopoietic stem cells obtained from a CD34.sup.Type: GrantFiled: May 3, 1993Date of Patent: January 25, 2000Assignee: Surrogen, Inc.Inventors: Armand Keating, Dong-dong Wu
